This indicator comes on when the ignition key is turned
to the ªACCº or ªONº position. It goes off after about 6
seconds. This means the SRS airbags are operating
properly.
The SRS airbag warning light system monitors the airbag
sensor assemblies, inflators, warning lights, interconnecting
wiring and power sources.The SRS airbag system is designed to activate in
response to a severe frontal impact within the shaded
area between the arrows in the illustration.
The SRS airbags will deploy if the severity of the impact is
above the designed threshold level, comparable to an
approximate 20 km/h (14 mph) collision when impacting
straight into a fixed barrier that does not move or deform.
If the severity of the impact is below the above threshold
level, the SRS airbags may not deploy.
However, this threshold velocity will be considerably higher
if the vehicle strikes an object, such as a parked vehicle or
sign pole, which can move or deform on impact, or if it is
involved in an underride collision (e.g. a collision in which the
nose of the vehicle ªunderridesº, or goes under, the bed of
a truck).
It is possible with collision severity at the marginal level of
airbag sensor detection and activation that only one of your
vehicle's two airbags will deploy.

belts.

Collision from the side
Collision from the rear
Vehicle roll±over
The SRS airbags are not designed to inflate if the
vehicle is subjected to a side or rear impact, if it rolls
over, or if it is involved in a low±speed frontal collision.

SRS airbag warning light
The airbag sensor assembly consists of a safing sensor and
airbag sensor.
In a severe frontal impact, sensors detect deceleration and
the system triggers the airbag inflators. Then a chemical
reaction in the inflators momentarily fills the airbags with
non±toxic nitrogen gas to help restrain the forward motion of
the occupants.
When the airbags inflate, they produce a fairly loud noise and
release some smoke along with the nitrogen gas. This is not
harmful and does not indicate a fire. Be sure to wash off any
residue as soon as possible to prevent minor skin irritation.
